Bug #36364: Clear all caches with IE9 results in blank page - TYPO3 Core - TYPO3 Forge

Same here on 4.7.4 on IE9 getting redirected to typo3/tce_db.php?vC=ddecc20f13&cacheCmd=all&ajaxCall=1&formToken=4c282815582849f4e99c4e59b5cafba0d17d0c5f

Getting a bit annoying for editors. :)

File 36364_v1.diff 36364_v1.diff added

The very old version of prototype (1.6.0.3) from 2008 has problems with the changed event handling of IE9.
There are several solutions to that, described e.g. here http://mandagreen.com/prototype-1-6-event-stop-ie9-quick-patch/:

Update to prototype 1.7, which is a no-go for at least 4.7
run the backend in IE8 compat mode like 4.5, which also is a no-go
patch prototype sources, also not an option for the backend usage
not using prototype event handling for the click events in the menu, but using the native ones. Shouldn't be there more broken modules in IE9 then?

Please test the attached patch (applies to 4.7 and 6.0). I went for option 4. and removed the Event.observe code and replaced it with onclick calls.
IE9 and IE10 in my virtual machines sent out the Ajax request and cleared the cache successfully.
